You’ll also have the problem we already have today, where individuals would construct their lives around a closely held corporation. When the corporation is closely held, income is supposed to pass through to the individual for taxation, but the incentives to evade theose rules would be much stronger.
In my perfect world most government revenue would come from land value taxes, with a smattering of Pigovian taxes on top, to the extent that the bureaucracy required to levy them wasn’t too onerous.
My ideal practical tax would be just a straight sales tax and nothing else. Income = Consumption + Savings, and since we want to encourage savings and investment it seems better and simpler to just do it that way.
Total libertarian dream scenario is no taxes, and government funds it self via slight inflation as a tax.
The first 6/7 is a condescending description of something obvious that doesn't respond to the OP's post, then reads histrionics into the post, then in the final sentences veers towards a real explanation, only to leave the rest as an unobvious exercise to the reader.
Point is, if you are upset, and I'm not trying to say that you shouldn't be, then the focus should be on the difference between tax on income vs capital gains / dividend income.
